Subject [jira] [Created] (HADOOP-8408) MR doesn't work with a non-default ViewFS mount table and security enabled
Date Fri, 18 May 2012 01:24:06 GMT
Aaron T. Myers created HADOOP-8408:
--------------------------------------

             Summary: MR doesn't work with a non-default ViewFS mount table and security enabled
                 Key: HADOOP-8408
                 URL: https://issues.apache.org/jira/browse/HADOOP-8408
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 2.0.0
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers


With security enabled, if one sets up a ViewFS mount table using the default mount table name,
everything works as expected. However, if you try to create a ViewFS mount table with a non-default
name, you'll end up getting an error like the following (in this case "vfs-cluster" was the
name of the mount table) when running an MR job:

{noformat}
java.lang.IllegalArgumentException: java.net.UnknownHostException: vfs-cluster
{noformat}
